COMBINED FAN AND ALARM SIGNAL.

Specification of Letters Patent.

Patented Jan. 15, 1918..

Application filed September 9, 1913. Serial No. 788,927.

To all whom it may concern: l V

Be it known that I, HERBERT HASTINGS, a citizen of the United States,residing at Brighton, in the county of Monroe and State of New York,have invented a new and useful Combined Fan and Alarm-Signal, of whichthe following is a specification.

My invention relates more particularly to fans and alarm signals as maybe used on automobiles, the former for directly or indirectly coolingthe engine and the latter as an alarm signal to indicate, at the will ofthe operator, the approach of the automobile, and the objects of myinvention are first, to combine these two mechanisms into one unit;second, to utilize the rotation of the fan for vibrating the diaphragmof the signal; third, to obtain greater power than is practical toobtain in the present electric horns and thereby a louder signal or oneof more volume of sound; fourth, to provide means for varying the volumeof sound at the will of the operator. The objects in the spirit of theinvention may be attained in many different arrangements and combination of parts. I show however the construc tions and combinationsillustrated in the drawing in which Figure l is a partial sectional viewthrough the axis of a device embodying my invention, by which I show aconstruction in which the vibrating diaphragm and sound amplifying hornrevolve with the fan element. c

Fig. 2 is a partial sectional view through the axis of a deviceembodying my invention by which I show a construction in which thevibrating. diaphragm and sound amplifying horn are stationary withrespect to the fan element.

Fig. 3 is a view in elevation looking at the front or right hand head ofthe fan drum of Fig. 2 showing apertures to. facilitate the issue ofsound from the alarm.

Fig. 4 is a partial view in perspective showing the slotted end of thehollow axle of Fig. 1. c

Fig. 5 is a partial View in perspective showing the flattened head end,with teeth thereon, of the vibration-producing element of Fig. 1.

Like numbers refer to like parts in the different views.

In Fig. 1, 1 is the bracket or arm which supports the assemblage,usually between the front of the engine and the rear of the radiator.This arm is pierced at its upper end to receive the stationary hollowaxle '2 which has an enlarged end 2 slotted transversely at 2 to receivethe flattened head 6 of the vibrator stem 3 to prevent the latter fromturning. The axle is threaded at 2 and 2 to receive the nuts 4: and 5respectively and the lever (i is also fitted to the threaded end 2. Thenut 4; serves to draw the bearings of the revolving element into properadjustment against the head 2 of the axle and also serves when soadjusted, as a shoulder on the axle which the tightening of the nut 5draws against the face of the arm 1 thus clamping the axle 2 securely inposition on the arm. The lever 6 has an elongated hub portion 6 which isthreaded internally to receive the adjusting screw 7 and the latter isprovided with a check nut 8 to secure it in adjusted position in thelever. The screw 7 is also threaded internally to receive the threadedend 3 of the vibrator stem The threads 2 and 3 are right and left hand,and as the lever (3 caused to turn on'the threads 2 of the axlethesethreads give it axial motion, and since the vibrating stem 3 is heldfrom rotation the threads within the screw 7 engaging with the threads 3of the vibrating stem 3 also give this stem axial motion which is thesum of the axial movements caused by the threads within the lever andthe threads upon the stem. This axial movement ,of thevibrator stem isfor the purpose of bringing the projecting teeth 3 provided 'on the headend thereof into and out of engagement with the projections on the shoeor vibrating block 9 which in turn is secured to the vibratingdiaphragm9. Supported by suitable bearings on the hollow axle 2 is the fan body10 which is provided with a belt pulley portion 10, a flange 10 to guidethe belt on one side, an offset flange l0 with the three-fold purpose ofguiding the belt on the oppositeside, of forming one side of the soundbox of the signal and of providing a flange against which the vibratorydiaphragm 9 is held by being clamped between it and the flange 11 of thehorn 11 by the screws 12 which also pass through the flange 13 of thefan blades 13. It will thus be seen that while the fan is rotating thedia phragm of the signal rotates with it but normally out of contactwith the vibration producing element except as the latter is broughtinto contact by operating the lever (i and operating this lever more orless will vary the volume of sound by causing the diaph 'agm to havegreater or less vibratory motion.

In Fig. 2 the stationary axle 2 is secured in the supporting arm 1 bythe nut 5 which is threaded to the end'thereof, the tightening of thisnut drawing the axle collar 2* back toward the support, drawing thesound 'box 14: against the spacing collar 15 which in turn bears againstthe inner member of the bearing 16 and binds these parts securelyagainst the arm 1'. The outer member of bearing 16 is mounted in therotating head 17, to which is secured the vibration producing ring 18which is provided with projecting teeth 18 which contact with the pin 19which is supported in a suitable bearing in box It and is normally heldout of contact therewith by the expansive pressure of a coil springwhich surrounds the small diameter and presses against the shoulder oithe head portion 19 thereof; this pin is projected -into contact withthe teeth 18" by pulling the lower end of the lever 20 which is pivotedin suitable bearings on the arm 1, to

tion 23 transmits the vibration to the vibrating diaphragm 24 to whichthe shoe 23 is secured; the diaphragm 24: is held at its :outer diameterbetween the flange 14: of the stationary sound box let and the flange 25of the amplifying horn 25 by the screws .26.

' Secured to 'tlielrflange 17*"- of the head 17 is the tan body 27 whichis provided with belt flangesQT and 27", the flange 27 to which the fanblades 28 are secured and the perforated head portion 27 with openingsE, and the hub27 in which is held the outer member of the anti-frictionbearing 2-9 the inner member of which is mounted on the small end of theaxle 2 and on this small end are threaded the check nuts 30 whichprovide adjustment for proper running condition of the .bearings 16 and29. It will thus be seen in said support.

means for moving that the sound producing element is normallyinoperative and stationary with respect to the revolving tan andvibration producing ring revolving therewith but that contact may bemade between the latter and the sound producing element at. thewill ot'the operator. =1

I am awarethat prior to my invention alarm signals have been made withvibrating diaphragm and that fans have beenmade journaled on astationary axlesecured to a supporting arm] I do not therefor'e claimeither of these broadly but Iclaim l.'In a signal the combination of are -volving tan, a diaphragm mounted on the fan and rotatingtherewith,means to vibrate said diaphragm consisting of a projection on saiddiaphragm and a striking device "for striking said projection, aspindleon which said fan is mounted to rotate, a stem movable endwisethrough said spindle, said striking device being carried on the end ofsaid stem and-being movable thereby into and out of engagement with theprojection on said diaphragm.

2. In a'signal, the combination of'a tubular support, a horn mounted torotate about said support, a diaphragm circumferentially supported insaidhorn, projections on said diaphragm, a stem mounted to movelongitudinally through s'aidsupport to engage with the projections onsaid diaphragm, and means for moving said stem longitudinally In asignal, the combination of a tubular support, a tan mounted to rotateabout said support, a diaphragm circumferentially supported in said fan,projections on said diaphragm, a stem mounted to move longitudina'lly'through said support to engage with the projections on said diaphragm,and said stem longitudinally in said support. I

4. In a signal, the combination of a'tubular support, a hornmounted torotate about said support,a diaphragm circumferentially supported insaid horn, a projection on said diaphragm and a stem mounted to movelongitudinally through said support to engage with the projection onsaid diaphragm.
